Queries the maximum current limit on a channel if the channel is set to the specified voltageLevel.

Syntax

ViStatus _VI_FUNC niDCPower_QueryMaxCurrentLimit(ViSession vi, ViConstString channelName, ViReal64 voltageLevel, ViReal64 *maxCurrentLimit)

Parameters

NameDirectionTypeDescription
vi[in]ViSession

Identifies a particular instrument session. vi is obtained from the niDCPower_InitializeWithIndependentChannels function.

channelName[in]ViConstString

Specifies the channel to query. The maximum current limit may only be queried for one channel at a time.

Specify the channel using the form PXI1Slot3/0, where PXI1Slot3 is the instrument resource name and 0 is the channel.

voltageLevel[in]ViReal64

Specifies the voltage level to use when calculating the maxCurrentLimit.

maxCurrentLimit[out]ViReal64 *

Returns the maximum current limit that can be set with the specified voltageLevel.

Returns
